Demand and uses for helicopters on the rise

Aviation Week features a story on strong demand for helicopters and the services they perform.

Helicopters are needed for missions ranging from oil exploration to emergency medical services. The demand is so strong that manufacturers are working harder than ever to keep up.

The story also reports how newer helicopters use automatic dependent surveillance-broadcast(ADS-B) to fly in areas such as the Gulf of Mexico.

ADS-B networks track helicopters and relay their altitude, speed, and direction. This information is used to monitor and co-ordinate helicopter traffic over a wide area.
